PURPOSE:To eliminate the noise effectively even if the ground of a capacitor electronic apparatus is not enough and aim at the miniaturization by internally containing the common mode choke coil. CONSTITUTION:A modular jack internally contains the common mode choke coil 22, and the coil 26 for composing that common mode choke coil 22 and a contact 28 to the opposite plug and a connection pin 30 to the circuit substrate, etc., are integrally formed. Thereby, even if the ground is not enough, the noise is effectively eliminated, and the modular jack can be miniaturized, and the space is saved in comparison with the case that the common mode choke coil is separately arranged. |
